What this product is made from

The channel bodies to a length of 120 cm are made of formed stainless steel V4A (material no. 1.4404 = AISI 316L). The channel bodies have an adhesive flange with a pre-adhered KERDI collar. This material is a waterproofing membrane of soft polyethylene with a special fleece fabric laminated on both sides.

Depending on the type, the drain bodies are made of high-impact resistant acrylonitrile butadiene styrene (ABS).

The odour trap is made of acrylonitrile butadiene styrene (ABS).

The channel support is made of high impact resistant, expanded polystyrene (EPS).

Material properties and areas of application

The channel bodies, frames and grates are classified as K3 according to DIN EN 1253, Gullies for buildings. This class refers to areas without vehicle traffic, e.g. wetrooms in apartments, nursing homes, hotels, schools, and public washroom and shower facilities.

Channel bodies, frames and grates are suitable for wheelchair traffic.

KERDI-LINE in the brushed stainless steel V4A version (material no. 1.4404 = AISI 316L) is especially suitable for applications requiring resistance against chemical exposure and high mechanical stresses.

Even stainless steel of quality 1.4404 is not resistant to all chemical stresses such as hydrochloric and hydrofluoric acid or certain chloride and brine concentrations.

In certain cases, this also applies to seawater pools. The suitability of a proposed floor drain system must be verified based on the anticipated chemical, mechanical and/or other stresses. Aggressive cleaning products should not be used.

How to look after this product

The set includes a special cleaning brush with instructions for simple periodic cleaning of the odour trap and the channel body.

All cleaning agents must be free of hydrochloric and hydrofluoric acid.

Avoid contact with other metals, such as regular steel, to prevent corrosion. This also includes installation tools such as trowels or steel wool, e.g. for the removal of mortar residue.

Do not use abrasive cleaning agents on the sensitive surfaces (especially for EP = polished stainless steel).

We recommend the use of the stainless steel cleaning polish Schlüter-CLEAN-CP.
